1999-02-17 Floyd Mayweather w pts 12 Carlos Rios, Van Andel Arena, Grand Rapids, Michigan, USA - WBC. Referee: Dale Grable. Scorecards: 120-110, 120-109, 119-108. In what was virtually a shut-out win for the champion, Rios (129) proved himself to be able to take anything thrown at him, while constantly going forward in an effort to land punches of his own. Even though his attempts to damage Mayweather (130) were almost all futile, apart from having minor successes in the opening two rounds, he never gave up trying. The last two sessions saw Mayweather raining in all manner of blows as he desperately tried for a knockout, while Rios merely took them and came back for more.
